AXLE-CUTTER.

SPECIFICATION forming part of LettersPatent No. 477,268, dated June 21,1892.I

v Application filed August 3l, 1891..' Serial No. 404,203. (No model.)

To all whom it may concern:

Be it known that we, DAVID E. REED and ORLANDO GURNEE, citizens of theUnited States, residing at New Hudson, county of Oakland, State ofMichigan, have invented a certain new and useful Improvement in Axle-Outters; and We declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference being had tothe accompanying 1c llrawings, which form a part of this specificaion.

Our invention relates to axle-cutters for cutting back the end andshoulder of an axle for the purpose of readjusting the hub on the wheel;and it consists in certain improvements (hereinafter specificallydescribed) for adjusting the axle relative to the tool and in improvedmethods of feeding the tool.

The special feeding mechanism used we also desire secured to us for usein other combinations than that shown on axle-cutters.

In the drawings, Figure 1 is a perspective of our device. Fig. 2 is avertical section. Fig. 3 is an end elevation showing method of grippingthe axle and means for adjusting it. Fig. et is a view showing detailsof the external portion of the feeding mechanism.

In the drawings, A is the plate, in which is sleeved the tool-shaft Dand feeding-spindle O.

B is the plate, carrying the movable jaws for gripping and holding' theaxle. The plates A and B are connected by bolts or rods a2. These boltsmay be cut down at each end and provided with right and left screws,respectively, so as to screw the two plates A and B together to makethem into one frame-work for supporting the working parts of themachine. On the outer plate B is bolted the lower' jaw B', and which isprovided with slotted bolt-holes b for vertical adjustment. To the jaw Bis attached the upper jaw B2, the distance between the jaws beingregulated by the set-screws b b', thus providing for axles of differentsizes. The vertical adjustment of the lower jaw B' permits the axle tobe centered with relation to the tool-holder. The sleeve A of thevplateA is provided with an internal thread a. The sleeve or spindle C isprovided with an external thread c to correspond and engage with theinternal thread in the sleeve and has on each side of i the thread cjournal-bearings c and c2, working in corresponding bearings a4 and a5of the sleeve A.

On the outer end of the sleeve or spindle O is mounted the ratchet-wheelC. Mounted in the sleeve or spindle O is the tool-shaft D, provided onits inner end with a thread to engage the tool-head E and on its outerend with a square end to receive the crank F. Rotary motion to the headEis given by the crank F, and an endwise movement is given to thetool-shaft I) and the tool by rotating the sleeve or spindle O in thethreaded portion of the plate A.

' The tool is provided with an inner bearing which abuts against theinner end of the sleeve C, so that when the sleeve is moved inward, byrevolving it in the frame through the operation of the screw it forcesthe toolhead inward toward the axle'held between the jaws on the plateB.

The means employed by us for automatically feeding the cutter are asfollows: On the side of the sleeved portion A' of the plate A, I providea projection or lug G. In the outer end of this lug is Ithe projectingpin g, on which is mounted a lever g', having a free movement thereon.On the outer end of the arm g is the pawl g2, engaging with theratchet-wheel O. On the opposite end of the lever g is a rigid pawl orarm g3, adapted to prevent backward revolution of the ratchetwheel afterit has been advanced by the pawl g2. The crank F is provided on the endopposite the vhandle f with a pinV f projecting inward from the crankand adapted at each revolution of the crank to strike against the outerend of the lever g and as it passes the end of the lever operate thepawl g2 to move the ratchet-wheel one or more points. The pin f has aslotted connection with the end of the crank-arm, so that it may bemoved inward toward the pivot of the crank, and thus strike the lever gnearer its pivot and give the pawl g2 an increased throw, so as to movethe vratchet-wheel C any number of points desired within a certainlimit. This feeding mechanism just described, with its adjustable feedin the way of the pin having a slotted connection with the crank foradjusting the movement of the pawl, we believe IOO to be new, generally,as well as specifically, in a gear-cutter.

The operation of our device is as follows: The axle to be cut is xedbetween the jaws B and B2 and is centered relatively to the tool-holderby adjusting the jaw B on the face of the plate B. In the tool-holderare mounted tools e and e in the usual manner, and which may be set theouter one to cut back Ithe shoulder and the inner one to cut off the endof the axle. The ratchet-wheel may now be turned by hand until the toolsengage with the axle, and on revolving the tool. holder by means of thecrank the feeding mechanism will on each revolution of the crank feedthe ratchet-wheel one or more points, and by reason of the threadedc0nnec. tion of the sleeve C with the sleeve portion of the plateA willforce the tool-head inward` and cause it to feed or cut away the end ofthe axle, as desired.

We are aware that it is not new to cut back axles in this manner or tofeed the head by means of a sleeved shaft and spindle; but we are notaware that any means have been used for automatically feeding` the toolwhile cutting back the axle.

We are not aware that the adjustment for the purpose of centering theaxle relative to the tool-holder has ever been accomplished by adjustingthe jaws on the outer end of the frame in the manner shown anddescribed.

What we claim is- 1. In an axle-cutter, the combination of the plates Aand B, the jaw B, having a vertical adjustment on the plate B, and thejaw B2,

adjustably engaged with the jaw B', substantially as described.

2. In an axle-cutter, the combination of a frame, a sleeve having athreaded connection with said frame and adapted to feed forward on beingrotated therein, a spindle rotatably mounted in saidsleeve and providedwith a tool-head, a ratchet-Wheel on said sleeve, a crank on saidspindle provided with an adjustable pin, and a pawl operated by the pinand adapted to rotate said ratchet-wheel and sleeve one or more pointson each revolution of said crank, substantially as described.

3. In anI axle-cutter, a feeding mechanism consisting of lever g',pivoted to the frame of said cutter, and pawl g2 and pin f', mounted inthe crank of said axle-cutter, substantially as described.

4. In an axle-cutter, a feeding mechanism consisting of lever g and pawlg2, in combination with crank F, and pin f', having a slotted connectionwith said crank, whereby the throw of the lever g may be increased ordiminished,substantially as described.

5. In an axle-cutter, feeding mechanism consisting of threaded sleeve C,ratchet-Wheel C', lever g', pawl g2, rigid pawl g3, and crank F,provided with pin f', substantially as described.

In testimony whereof we sign this specifica tion in the presence of .twoWitnesses.
